The assertion is caused by too large a data packet (0xe,../../Source//nps_8011/pts/np_d6_buf.c,279d6_get_buf err: size=15064 too big) received by the NE40. It is an error packet or other cause on the network and will have no effect on the operation of the NE40. The NE40 usually may receive two types of packets during operation. One type is the packets that the NE40 needs to forward. Most packets are of this type. No matter how large these packets are, the NE40 fragments them according to the MTU. Therefore, these packets have no effect on the NE40. The other type is packets that are sent to the NE40, including ping packets and protocol packets. Packets of this type need to be sent to the main control board and the size of these packets cannot exceed 15000 bytes. If the size exceeds 15000 bytes, the above assertion occurs. Usually, there are no such large ping packets or protocol packets and the assertion is caused by error packets. Therefore, you do not need to worry about how many times the assertion occurs.
